2011년 3월 11일에 일본 토호쿠 지역에서 발생한 대지진은 일본뿐만 아니라 한반도에도 지각변동을 발생시켰다. 이 논문에서는 토호쿠 지진에 의한 국내 GPS 기준점의 좌표 변동을 분석하여 국토지리정보원의 고시좌표와 비교하였다. 그 결과 토호쿠 지진에 의해 한반도는 남북방향으로 평균 -0.8cm, 동서 방향으로 평균 3.5cm, 그리고 수직방향으로 -4.0cm의 변동이 있었음을 알 수 있었다.
Abstract
The great Tohoku-oki earthquake which occurred on March 11, 2011, caused crustal movements in both Korea and Japan. This study attempts to analyze the amount of coordinate shift of GPS reference stations on Korea Peninsula due to the Tohoku-oki earthquake and to compare the published coordinates by National Geographic Information Institute (NGII). As a result, we found that the average coordinate shift of South Korea is -0.8cm northward, 3.5cm eastward, and -4.0cm in vertical direction; when this figure is compared with the past crustal movements of the Korea Peninsula.
